The window restrictor (10) of the present invention may be used to limit the opening of a casement hinged window. The restrictor (10) comprises a restrictor member (12) and a latch mechanism (14). Typically, the restrictor member (12) is attached to a stile or rail (16) of the moving window pane and the latch mechanism (14) is attached to a part of the casing or frame 18 surrounding the window opening. In use, the restrictor member (12) is engaged with the latch mechanism (14) so that as the window is opened, the extent of opening is restricted by the length of the restrictor member (12). To fully open the window, the restrictor member (12) must be disengaged from the latch mechanism (14). When the restrictor member (12) and latch mechanism (14) are disengaged, they remain in such a configuration that, when the window is closed, the restrictor member (12) and latch mechanism (14) automatically re-engage to prevent the window being fully opened again. This means that it is not necessary to remember to reattach or reset the restrictor (10) each time the window is opened and closed. In addition, the restrictor member (12) comprises a hinged member which includes bias means which urges the restrictor member to lie adjacent to and flush with the window pane in the fully opened and disengaged position.
A window restrictor for limiting the extent of opening of a window, the window restrictor comprising a restrictor member attachable to a first part of a window and a latch mechanism attachable to a second part of the window, the restrictor member comprising a first arm and a second arm, wherein the first arm comprises attachment means to rotatably attach the first arm to the first part of the window, the first arm being pivotally connected to the second arm and the second arm comprising a first locking means, the latch mechanism comprising second locking means for engagement with the first locking means, wherein, in use, when said first and second locking means are engaged, relative movement of said first and second window parts in a direction of opening is limited by said restrictor member, the window restrictor further comprising release means for disengaging said first and second locking means to enable the relative movement of said first and second window parts beyond the limit of the restrictor member and, when disengaged, the first and second locking means are aligned to automatically reengage as the window is closed and wherein the release means comprises a simultaneous dual action release mechanism comprising a first actuator and a second actuator and wherein the first actuator is operated by a first manual action and the second actuator is operated by a second independent manual action.
A window assembly including a window and a window restrictor for limiting the extent of opening of the window, the window restrictor comprising a restrictor member attachable to a first part of a window and a latch mechanism attachable to a second part of the window, the restrictor member comprising a first arm and a second arm, wherein the first arm comprises attachment means to rotatably attach the first arm to the first part of the window, the first arm being pivotally connected to the second arm and the second arm comprising a first locking means, the latch mechanism comprising second locking means for engagement with the first locking means, wherein, in use, when said first and second locking means are engaged, relative movement of said first and second window parts in a direction of opening is limited by said restrictor member, the window restrictor further comprising release means for disengaging said first and second locking means to enable the relative movement of said first and second window parts beyond the limit of the restrictor member and, when disengaged, the first and second locking means are aligned to automatically re-engage as the window is closed and wherein the release means comprises a simultaneous dual action release mechanism comprising a first actuator and a second actuator and wherein the first actuator is operated by a first manual action and the second actuator is operated by a second independent manual action.
A method of limiting the extent of opening of a window with a window restrictor, the method comprising attaching a restrictor member to a first part of the window and attaching a latch mechanism to a second part of the window, the restrictor member comprising a first arm and a second arm, wherein the first arm comprises attachment means to rotatably attach the first arm to the first part of the window, the first arm being pivotally connected to the second arm and the second arm comprising a first locking means, the latch mechanism comprising second locking means for engagement with the first locking means, wherein, in use, when said first and second locking means are engaged, relative movement of said first and second window parts in a direction of opening is limited by said restrictor member, the method further comprising providing release means for disengaging said first and second locking means to enable the relative movement of said first and second window parts beyond the limit of the restrictor member and, when disengaged, the first and second locking means are aligned to automatically reengage as the window is closed and wherein the release means comprises a simultaneous dual action release mechanism comprising a first actuator and a second actuator and wherein the first actuator is operated by a first manual action and the second actuator is operated by a second independent manual action.
